There's more paperwork for them when people use guns (both law abiding citizens and criminals alike). In general guns create more risk and more work for them.
Saving your life and the life of somebody is more worth every paperwork. So, what do we do discourage the law abiding citizen and have the criminals a free rein. If it creates more risk all the other states that believe in 2A rights would've have their crime rate go up, but instead it went down. How many times you hear on the news about guys roaming that have like 40 prior convictions and yet you worry about the law abiding citizen.
"Taking my gun away because I might shoot someone is like cutting my tongue out because I might yell `Fire!' in a crowded theater."
-Peter Venetoklis
"The world is filled with violence. Because criminals carry guns, we decent law-abiding citizens should also have guns. Otherwise they will win and the decent people will lose."
-James Earl Jones
"Laws that forbid the carrying of arms...disarm only those who are neither inclined nor determined to commit crimes. Such laws make things worse for the assaulted and better for the assailants; they serve rather to encourage than prevent homicides, for an unarmed man may be attacked with greater confidence than an armed one."
-Thomas Jefferson
Lastly, didn't they took an oath to support and defend the constitution?
